Book excerpt: DuBois Creek Dam is located on DuBois Creek, approximately 2.1 miles southwest of Hartford, Pennsylvania. The inspection was performed on 28 October 1980. A light rain was falling at the time of inspection. The dam and appurtenant structures were found to be in poor overall condition at the time of inspection. Seepage was observed at three locations passing through deteriorated portions of the concrete core wall. These seepage areas are the result of progressive deterioration of the exposed areas of the concrete core wall. The seepage has caused erosion gullies and slight irregularities on the downstream face of the dam.

Dziubek and published by . This book was released on 1981 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Warner Dam is owned by William S. Newlin, Jr., and is classified as a 'Low' hazard - 'Small' size dam. The dam was found to be in fair overall condition at the time of inspection. Hydraulic/hydrologic evaluations revealed that the spillway capacity is less than the peak inflow to the impoundment during the 100-year flood. A spillway design flood (SDF) in the range of the 50- year flood to the 100-year flood is required for Warner Dam. The 100-year flood was chosen as the SDF. The spillway is therefore considered 'Inadequate.' It is recommended that the owner immediately develop remedial measures to provide adequate spillway capacity. The inspection revealed certain items of remedial work which should be performed by the owner without delay. These include: (1) Provide adequate spillway capacity; (2) Repair the spalling on the downstream face of the concrete corewall; (3) Ensure that the outlet works are operable, or develop an emergency drawdown plan; and (4) Cut all trees on the embankment at ground level. All trees with a trunk diameter greater than 3 inches should have their root systems removed. All resultant areas of erosion and cavities should be filled, graded, compacted and seeded. In addition, the following operational measures are recommended to be undertaken by the owner: (1) Develop a detailed emergency operation and warning system; (2) During periods of unusually heavy rainfall, provide around-the-clock surveillance of the dam; and (3) When warning of a storm of major proportions is given by the National Weather Service, activate the emergency operation and warning system.

This book was released on 1979 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam consists of a zoned, earthfill embankment that is 590 feet long and 52 feet high at its maximum section. The main spillway is a drop spillway located near the right abutment of the dam. It consists of a concrete riser connected to a 30-inch diameter reinforced concrete pipe under the embankment. The auxiliary spillway is an excavated channel along the left abutment of the dam. It is a grass-linked excavation in earth. Based on visual inspection, available records, calculations and past operational performance, PA-467 Dam is judged to be in good condition. The existing spillway can pass the Probable Maximum Flood(PMF) without overtopping of the dam. The spillway capacity is rated as adequate. There is a slope stability analysis for the embankment, and it indicates that the embankment has adequate factors of safety. There is no evidence of significant problems threatening the embankment.

This book was released on 1981 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: Page's Lake Dam is owned and operated by the Lakeside Outing Club and is classified as a 'Significant' hazard - 'Intermediate' size dam. The dam was found to be in good overall condition on 27 October 1980. Hydraulic/hydrologic evaluations, performed in accordance with procedures established by the Baltimore District, Corps of Engineers, for Phase I Inspection Reports, revealed that the spillway will not pass the 1/2 Probable Maximum Flood (1/2 PMF) without overtopping the dam. A spillway design flood (SDF) in the range of the 1/2 PMF to the Probable Maximum Flood (PMF) is required for Page's Lake Dam. The 1/2 PMF was chosen as the SDF because the dam is on the low end of the 'Intermediate' size category in terms of storage. During the 1/2 PMF, the dam is overtopped by a maximum depth of 3.34 feet for a total duration of 11.83 hours. The spillway is therefore considered 'Inadequate.' It is recommended that the owner immediately initiate an engineering study to further evaluate the spillway capacity and develop recommendations for remedial measures to reduce the overtopping potential of the dam.

This book was released on 1981 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest Lake Dam is located on Forest Lake Creek in Forest Lake Township, Susquehanna County, Pennsylvania. The original purpose of the impounded water was for ice harvesting and recreation. Additionally, water releases from the impoundment activated a saw mill. Presently, the lake is being used for recreation. The overall appearance of the dam is poor. Location of observed deficiencies are shown on the General Plan. The profile and typical sections of the dam are presented and are based on field survey made on the day of inspection. The survey datum for this inspection is elevation 1527 feet above mean sea level which is stamped on the USGS Bench Mark (No. TT15K, 1931) on the large sandstone slab, upstream of the service spillway. On the inspection date (12/10/1980), the lake was being drawn down for the winter. The lake level was approximately at elevation 1523.6, or 2.8 feet below its normal level. Deficiencies observed during the field inspection are described. Visible features are depicted in photographs.

This book was released on 1980 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a visual inspection, operational history, and available engineering data, the dam is considered to be in fair condition. The size classification of the facility is small and its hazard classification is considered to be high. In accordance with the recommended guidelines, the Spillway Design Flood (SDF) for the facility ranges between the 1/2-PMF (Probable Maximum Flood) and the PMF. Due to the high potential for damage to downstream structures and possible loss of life that could be associated with a sudden breach of the embankment, the SDF is considered to be the PMF. Results of hydrologic and hydraulic analysis indicate the spillway for Wadham Creek Dam is capable of passing and/or storing the PMF. Consequently, the spillway is considered adequate.

Michalcin and published by . This book was released on 1980 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a visual inspection, operational history, and available engineering data, the facility is considered to be in good condition. The size classification of the facility is intermediate and its hazard classification is considered to be high. In accordance with the recommended guidelines, the Spillway Design Flood (SDF) for the facility is the PMF (Probable Maximum Flood). Results of the hydrologic and hydraulic analysis indicate the facility will pass and/or store only about 45 percent of the PMF prior to embankment overtopping. A breach analysis indicates that failure under less than 1/2 PMF conditions could lead to increased downstream damage and potential for loss of life. Thus, based on screening criteria provided in the recommended guidelines, the spillway is considered to be seriously inadequate and the facility unsafe, non-emergency. Calculations also indicate that if the spillway were constructed in accordance with available desing drawings, the facility could pass and/or store approximately 63 percent of the PMF.

This book was released on 1979 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the inspection is to determine if the dam constitutes a hazard to human life or property. The dam consists of a homogeneous earthfill embankment that is 680 feet long and 64 feet high at its maximum section. The main spillway is a drop spillway located near the left abutment of the dam. It consists of a concrete riser connected to a 30-inch diameter reinforced concrete pipe under the embankment. One 12-inch by 21-inch uncontrolled orifice is located in the upstream face of the concrete riser with the orifice crest at El. 1227.0, which is 27 feet below design elevation of the top of the dam. The auxiliary spillway is an excavated channel at the right abutment of the dam. It is grass-lined except for portions that were excavated into rock. The hazard classification is high hazard. Downstream conditions indicate that a high hazard classification is warranted for PA-468 Dam. It is owned by the Susquehanna County Commissioners. Its purpose is for flood control.

This book was released on 1979 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on visual inspection (18 July 1979), available records, calculations, past operational performance, and according to criteria established for these studies, Lake Montrose Dam is judged to be unsafe, nonemergency, because the spillway capacity is rated as seriously inadequate. The existing spillway can pass only 17% of the Probable Maximum Flood (PMF) without overtopping of the dam. Based on the type of construction and the condition of the dam, it is judged that the dam could not withstand the depth and duration of overtopping that would occur for the PMF or the 1/2 PMF. Failure of the dam would cause an increased hazard to loss of life downstream. As a whole, the dam is judged to be in poor condition. The spillway has undergone a gradual structural failure that has resulted in a reduction of spillway capacity. Continuation of the gradual failure, or perhaps a sudden failure, appears to be possible. There are no functional outlet works for the dam. Maintenance of the project is inadequate. There is no program for regular inspection of the dam.

This book was released on 1981 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on visual inspection, Acre Pond Dam is judged to be in fair structural condition. In the absence of an adequate spillway, the dam is subject to frequent overtopping. Based on the location of the downstream dwellings and the fact that a few lives could be lost should the dam fail, the dam is classified as a significant hazard dam. Since the spillway cannot pass the 100- year flood without overtopping the dam, the spillway is rated as inadequate. Although there is some seepage thru the dam, there is no evidence of structural instability. There is no formal inspection and maintenance program or warning system and evacuation plan in effect at Acre Pond Dam. The dam is not properly maintained.
